r <br /> 3) Construct a treatment cell for the purpose of containing the <br /> affected soil. <br /> 4) Inoculate the selected microbes into the soil. Fertilize as <br /> necessary. <br /> 5) Irrigate the soil pile as needed to maintain sufficient water <br /> content. <br /> 6) Cover the treatment cell with plastic sheeting. <br /> 7) Obtain progress soil samples every 30 days to monitor <br /> degradation of hydrocarbon contaminants. One or two soil <br /> samples will be collected from the soil pile "hot spots" and <br /> analyzed for TPH as gasoline and BTE&X. <br /> 8) Collect soil samples at the completion of treatment <br /> (approximately 60 to 90 days) . Soil samples will be collected <br /> using a metric soil sampler loaded with two clean, 2 X 3-inch <br /> brass tubes. The ends of the lead tube will be covered with <br /> aluminum sheets, capped and sealed with tape. <br /> . 9) 3 Transport soil samples under chain-of-custody to a state- <br /> certified laboratory and analyze for TPH as gasoline and BTE&X <br /> in accordance with EPA methods 8015m and 8020, respectively. <br /> 10) Upon completion of treatment, prepare a brief report detailing <br /> the procedures and summarizing the results of the soil <br /> remediation. <br /> 11) Upon approval from the PHS/EHD, backfill the excavation and <br /> compact the soil to required standards. <br /> The opportunity to prepare this work plan is greatly appreciated. <br /> Please contact our office if you have any questions or comments. <br /> Sincerely, <br /> GEOLOGICAL AUDIT SERVICES, INC. <br /> Bob Marty V <br /> Project Manager <br /> 3 <br />
